I would like to have a 4'/22kg Radar antenna on a Sea Ray 315 Sundancer
Sport Spoiler, Molded Fiberglass (Seamless) w/Overhead Lighting.

Is this workable, as I do not seem to get an answer from SeaRay?
Or is there a lower weight limit so I would have to forego the
advantages of a big enough antenna?

Marc, let's take a look at reality on radar......

Radar cannot see further than the horizon.

Not true.

The horizon depends on how far UP the antenna is mounted.

Also not true.


Indeed. Also, the line of sight limitations for VHF radios are not hard
and fast. I've been out on the bay with my handheld VHF with its puck
antenna and successfully sent and received some days 2X line of sight and
maybe 3X. Other days, reception sucks. Even with a 25W "installed" VHF
with a top quality 8' antenna.

Cell coverage, at least on the parts of the Bay I frequent, is more
reliable.


I've been out 70 miles in the Gulf, and listened on the VHF to Tow Boat US
Palm Beach talk to a vessel in distress over on the East Coast.
